Title: Device for detecting transfer in and out of wafer
Inventor: HOSAKA SHIGETOSHI
IPC: B65H43/00
Filed: 1987-05-30
Abstract: PURPOSE:To sense the inclination of a wafer in a carrier before transfer and to effectively transfer the wafer by the arm of a delivering mechanism further even if the wafer is slightly inclined by position control of transfer in and out of the wafer by the outputs of at least two wafer position detecting mechanisms in the carrier. CONSTITUTION:A carrier placing base 16 is moved up and down, and the positions and parallel states of wafers 11 are detected by two optical sensors having light emitting units 14a, 14b and photodetectors 15a, 15b in this case. Thus, a position where an optical path is initially interrupted and a position where the path is then opened are stored in a memory, the distance between the two positions is calculated, and the distance is converted into an inclination. If the wafer 11 is erroneously contained in an inclined state in a carrier 12, the inclination of the wafer 11 can be detected on the bases of the data before an arm 13 delivers it. Further, the slightly inclined wafer 11 is set at its relative positions of the heights of the inclined position and the arm 13, the wafer 11 is so evacuated in vacuum as not to bring the arm 13 into contact with the wafer 11, and delivered from the carrier 12.

Title: Combustion appliance
Inventor: UEDA JUNICHI
IPC: F23C99/00
Filed: 1992-05-26
Abstract: PURPOSE:To stop combustion if a back fire occurs and to allow safety and low NOx compatible by stopping the combustion if a temperature sensor provided in a second mixture gas chamber formed to be surrounded by a burner body and an injection plate senses an abnormal temperature. CONSTITUTION:A temperature of lean mixture gas is raised by thick flame to be formed on a first burner port 1. A second burner port 15 is provided at an oblique part 13 to increase an area of the port thereby to reduce a flowing speed of the lean mixture gas, thereby performing complete combustion. However, since the port 15 becomes a high temperature, a back fire tends to easily occur, the back fire occurs in a mixture gas passage 7 by strong gas flow to possibly burn in a second mixing chamber 16. In this case, a temperature sensor 17 disposed at a downstream side of a mixture gas passage 7 senses a temperature of a flame formed on the passage 7 to stop supplying of gas, thereby stopping combustion.

Abstract: PROBLEM TO BE SOLVED: To surely transmit the data to many users by providing a constitution where a host transmiting the multicast data controls dynamically the constitution of a host group according to the state of a network. SOLUTION: A host 100 transmiting the multicast data 101 receives the transmission confirming notifications from the hosts 150-163 to its transmitted frames and manages both unreceived and normal reception states per frame to each of hosts 150-163.
